The TMP is obtained by forming a non-perishable, substantially solid material into a predetermined mass or shape, wherein the non-perishable material, in combination with the predetermined mass or size, has a temperature retention property similar to a perishable product; sealing an entirety of the formed material with a protective covering to form a core; accommodating a temperature sensor into a sensor side of the core; forming a first insulating layer on the sensor side of the core; and forming an enclosure of a second insulating layer that covers remaining sides of the core, wherein the first insulating layer is configured as a lid to the enclosure, wherein a change in temperature of a neighboring perishable product is substantially mimicked by readings from a temperature sensor in the core. ## Claims ### Claim 1 A method for fabricating a rapid chillable thermal mimicking probe (TMP) for use with perishable products, comprising: forming a non-perishable, substantially solid material into a predetermined mass or shape, wherein the non-perishable material, in combination with the predetermined mass or size, has a temperature retention property similar to a perishable product;
